At Gurtam, I designed and led a unified billing platform for five products, reducing duplicated billing logic by 80%. Its shared Python and PostgreSQL backend processes about €6M monthly across roughly 5,000 invoices.
I also automated payment ingestion and transaction processing across Stripe, PayPal, QuickBooks, Deel, and five banks. These event-driven workflows handle about 50,000 monthly transactions and reduced manual financial operations by 70%.
Previously, at UAB Sandas, I delivered a unified sales, billing, and field-service platform that saved more than 5,400 human hours in its first three months. At Draugiski sprendimai, I extended Odoo ERP with Shopify integrations that reduced manual data entry by about 70%.
